FAQ

Q: What certification does the product pass?

We normally do CE, E-Mark certification. We could do the certification based on different market and different customer’s requirement.


Q: Could we customize the amplifier?

Sure! We have our own R&D team can provide tech support. From SMT, AI, assembly, plastic injection, test, packing. We do all the process in house.

We specialize in designing and manufacturing consumer electronic products: Power Stations, Power Banks, Wireless Chargers, Wall Chargers, Car Chargers, Watch Chargers, Cables and Car Amplifiers since 2008.

With 30+ R&D team members, we have strong ability on developing innovation products. We offer both ODM and OEM projects for customers.


Q: How long does it take to test the aging of the power amplifier? What is the test standard time? What is the standard for the aging of the power amplifier?

For different models, the aging test time is different. Generally ranging from 15-30 minutes. The aging standard of the power amplifier is according to the RMS power aging, that is, according to the rated output power of the power amplifier. (RMS: refers to rated output power, which is the maximum power that can be continuously output.) Full name: Root Mean Square, literally translated as root mean square, translated as: valid value)


Q: What is Signal-to-Noise Ratio? Is it better to have a higher signal-to-noise ratio or a smaller value?

Refers to the comparison of noise when there is a signal and when there is no signal. This is usually a negative value, but is often expressed as a positive number for ease of viewing.

Assuming that the noise is 0 dB when there is a signal and 5 dB when there is no signal, then the signal-to-noise ratio is -5 dB, which is usually expressed as 5 dB. The higher the signal-to-noise ratio, the better.


Q: I want to customize a amplifier, how soon can I get a sample and then finish the MP1?

Normally we need 6~9 months to complete the development, then finish the pilot run in ~50 days. If we prepare the LLT components, we can finish the MP1 in ~60 days.
